Abstract

The invention belongs to the technical field of new material tire preparation, and relates to a preparation method of a graphene functional aviation tire. The technological process comprises the following five steps: preparing modified graphene, preparing compound tread rubber and sidewall rubber, preparing compound tread and sidewall, preparing a compound green tire and preparing an aviation tire. Based on specific functional characteristics of graphene material, on the basis of the modified graphene and a basic recipe of an aircraft tire in the prior art, 0.1 to 15 weight parts of modified graphene is added into the tread rubber and sidewall rubber separately, a plastic mixing and calendaring process is adopted, mould pressing bonding forming is carried out under high-temperature conditions with functional layers such as an air impervious liner, a buffer layer and a cord fabric according to a tire manufacturing basic technology, and finally the aviation tire is compositely prepared and obtained through subsequent fabrication processing of vulcanization; the technology is simple and practicable, the conventional production equipment is fundamentally utilized, large-scale technical transformation is not needed, the preparation method is applicable for the preparation of various types of aviation tires, and the preparation method is convenient for popularization and application.

Description

Technical field: [0001] The invention belongs to the technical field of tire preparation of new materials, and relates to a method for preparing a graphene-functional aviation tire, in particular, compounding modified graphene and colloidal materials to prepare an aviation tire compound with balanced physical properties. Background technique: [0002] Aviation tires are key components that affect the overall performance and safety of aircraft. During take-off and landing, the tires are equivalent to a cushioning air cushion. When the aircraft is taxiing and parking, the tires need to stably carry the full load of the airframe, especially when the aircraft is in the air. During take-off and landing, tires should be able to effectively dissipate impact energy, absorb and export friction and pressure heat energy, and should also have auxiliary braking force; the working environment of aviation tires requires them to have large load capacity, high inflation pressure, fast heat ge...
